BACKGROUND OF THE INVENTION Field of the Invention

The present invention relates to devices and methods for quickly and easily connecting electrical fixtures. More specifically, the present invention relates to a device and method for quickly and easily connecting overhead electrical fixtures such as lights or ceiling fans to a ceiling electrical box.

Description of the Related Art

Attaching electrical ceiling fixtures, such as lights or fans, to an electrical junction box set into the ceiling is a difficult task for a single installer. To install the fixture, it is lifted to just below the electrical junction box, and is held there while connecting the fixture wires to the electrical supply wires. After the electrical connection is finished, the fixture is lifted further to align mounting holes in the fixture's mounting plate with mounting holes in the junction box. Screws or bolts are then threaded through the mounting holes to secure the fixture to the junction box. The combined operation takes several minutes and usually requires two persons, one to lift and hold the fixture and the other to make the wire and screw connections.

U.S. Pat. No. 6,503,099 teaches a quick connect device for hanging fans, lighting fixtures, and the like. A horizontal sliding connector is provided between the ceiling box and the electrical fixture. The sliding connector takes the weight of the fixture as it is inserted, which can be done by one person. The electrical connections are established by a plug-and-receptacle connector positioned to engage automatically as the sliding connector slides into place.

However, the quick connect device of U.S. Pat. No. 6,503,099 does not include mechanisms for connecting the plates of the mounting device directly to the pre-set mounting holes in the ceiling box and fixture. Accordingly, there is a need for a quick connect mount for an electrical fixture that can be directly mounted to the pre-set mounting holes in the junction box and fixture. There is also a need for a method for connecting a ceiling mounted fixture directly to a ceiling junction box by way of the pre-set mounting holes provided in both the junction box and fixture.

As best shown in FIG. 1 -FIG. 5 , one presently preferred embodiment of the invention comprises a quick connect mounting assembly 10 which includes a first junction box mounting plate 20 and a second fixture mounting plate 30. It is within the scope of the invention to flip the plates such that the first mounting plate 20 is connected to the fixture 50 and the second mounting plate 30 is connected to the junction box 40, but for purposes of the detailed description, the first mounting plate 20 will be described as being connected to the junction box 40 and the second mounting plate will be described as being attached to the fixture 50.

The first mounting plate 20 has a plurality of bore holes 22 at opposing corners thereof that line up with and correspond to threaded bores 42 located in opposing corners of a standard ceiling electrical junction box 40. Bolts or screws 23 are inserted through holes 22 and engage the threads of the threaded bore holes 42 to secure the first mounting plate 20 to the ceiling junction box 40. Similarly, the second mounting plate 30 has a plurality of bore holes 32 at opposing corners thereof that line up with and correspond to threaded bores 52 located in opposing corners of a standard electrical fixture 50 such as the light fixture shown in FIG. 4A, FIG. 4B and FIG. 5 . Bolts or screws 33 are inserted through holes 32 and engage the threads of the threaded bore holes 52 to secure the second mounting plate 30 to the fixture 50.

A first electrical connector 24 is positioned in a channel 26 in the face of the first mounting plate 20. Electrical wires 28 have first ends connected to the first electrical connector 24 and second ends that pass through an opening in the first mounting plate 20 and travel to the interior of the junction box 40 where they are electrically coupled to the power supply in a conventional manner. As best shown in FIG. 3A, the side walls of the channel 26 are angled inwardly to receive the outwardly sloping walls of the mating projection 36 on the second mounting plate 30 (FIG. 3B). The second mounting plate 30 also includes a second electrical connector 34. Electrical wires 38 have first ends connected to the second electrical connector 34 and second ends that pass through an opening in the second mounting plate 30 for electrical coupling to the terminals of the fixture 50. As shown in FIG. 3A and FIG. 3B, the first electrical connector 24 is a female connector and the second electrical connector 34 is a male connector with male contacts configured to engage the female contacts of the first electrical connector 24 when the first mounting plate 20 and second mounting plate 30 are fully engaged.

In operation, the mounting plates 20, 30 are first attached to the junction box 40, and fixture 50, respectively. The wires 28 of the first mounting plate 20 are connected to the power source wires inside the ceiling junction box 40. The first mounting plate 20 is then attached to the junction box 40 by bolts or screws 23 that pass through the openings 22 in the first mounting plate 20 and threadably engage the threaded openings 42 in the junction box 40. The wires 38 of the second mounting plate 30 are connected to the terminals on the fixture 50. The second mounting plate 30 is then attached to the fixture 50 by bolts or screws 33 that pass through the openings 32 in the second mounting plate 30 and threadably engage the threaded openings 52 in the fixture 50.

Once both of the mounting plates 20, 30 are secured, the open end of the channel 26 of the first mounting plate 20 is lined up with the free end of the mating projection 36 of the second mounting plate 30. The second mounting plate 30 and the fixture 50 that is affixed thereto are then slid along the axis of the channel 26 until the electrical contacts of the first electrical connector 24 fully engage the electrical contacts of the second electrical connector 34. When this occurs, the first mounting plate 20 should be substantially in alignment with the second mounting plate 30. The fixture 50 may be removed by sliding the fixture 50 and associated second mounting plate 30 in the opposite direction until the walls of the projection 36 are clear of the walls of the channel 26.
